[0045] Example 1

[0046] like Figures 1-9 As shown, the first embodiment of this utility model provides a flipping device 100, which includes a mounting base 1, a rotating shaft 2, a bearing component 3, and a connecting component 4.

[0047] Mounting base 1 has a first through hole 111; rotating shaft 2 passes through the first through hole 111; bearing 3 is located between the outer wall of rotating shaft 2 and the hole wall of first through hole 111; connecting member 4 is fixedly connected to rotating shaft 2 and located on one side of mounting base 1.

[0048] Based on this technical solution, by placing the bearing component 3 between the first through hole 111 of the rotating shaft 2 and the mounting base 1, the coaxiality of the rotating shaft 2 and the mounting base 1 can be improved, thereby reducing the assembly gap between the rotating shaft 2 and the through hole, which in turn helps to reduce the shaking of the seat during the flipping process. The structure is simple.

[0049] The mounting hardware is used for mounting onto the vehicle body.

[0050] Connector 4 is used to connect the seat body.

[0051] The central axis of the rotating shaft 2 is the first axis.

[0052] See Figures 1-3 ,and Figure 5 and Figure 6 The flipping device 100 provided in Embodiment 1 of this utility model further includes a locking nut 5; the outer wall of the rotating shaft 2 is provided with a first external thread 2111, and the locking nut 5 has a first threaded hole 521. The locking nut 5 is threadedly connected to the first external thread 2111 through the first threaded hole 521. The locking nut 5 is located on the side of the mounting base 1 away from the connecting member 4. In this way, the mounting base 1 and / or the bearing member 3 can be squeezed by tightening the locking nut 5 during assembly, so as to play the role of self-alignment and reduce the assembly gap, thereby helping to further reduce the shaking of the seat during the flipping process.

[0053] In this embodiment, the bearing component 3 includes two bearings, namely the first bearing 31 and the second bearing 32.

[0054] In some other embodiments, the bearing component 3 may also include any number of bearings, such as one, three, four, or five, and this is not limited here.

[0055] See Figures 1-6 The flipping device 100 provided in Embodiment 1 of this utility model also includes a mounting bracket 6.

[0056] Mounting base 1 includes a first side plate 11, a first base plate 12, and a second side plate 13. The first side plate 11 is connected to one end of the first base plate 12, and the second side plate 13 is connected to the other end of the first base plate 12 and is disposed opposite to the first side plate 11. Both the first side plate 11 and the second side plate 13 have a first through hole 111, and a first receiving groove 121 is formed between the first side plate 11, the first base plate 12, and the second side plate 13.

[0057] The mounting bracket 6 is located in the first receiving groove 121. The two ends of the mounting bracket 6 are respectively connected to the first side plate 11 and the second side plate 13. The mounting bracket 6 has a second through hole 611. The locking nut 5 is located on the side of the first side plate 11 away from the mounting bracket 6.

[0058] The rotating shaft 2 includes a first shaft body 21 and a second shaft body 22 connected in sequence. The first shaft body 21 passes through the first through hole 111 and the second through hole 611. The second shaft body 22 is located on the side of the second side plate 13 away from the mounting bracket 6. The connector 4 is fixedly connected to the second shaft body 22.

[0059] The first bearing 31 is disposed between the wall of the first through hole 111 of the first side plate 11 and the outer wall of the first shaft 21, and the second bearing 32 is disposed between the wall of the first through hole 111 of the second side plate 13 and the outer wall of the first shaft 21.

[0060] The diameter of the second shaft 22 is larger than the diameter of the first shaft 21, and the end of the second shaft 22 near the second side plate 13 abuts against the second bearing 32.

[0061] By placing the first side plate 11 between the locking nut 5 and the mounting bracket 6 and placing the first bearing 31 in the first through hole 111 of the first side plate 11, the locking nut 5 can be tightened during assembly so that the locking nut 5 and the mounting bracket 6 can approach each other and press the first bearing 31, thereby achieving self-alignment and reducing assembly clearance. At the same time, since the second side plate 13 is located between the mounting bracket 6 and the second shaft 22, tightening the locking nut 5 can also allow the mounting bracket 6 and the second shaft 22 to approach each other and press the second bearing 32, thereby achieving self-alignment and reducing assembly clearance.

[0062] In this first embodiment, both the first bearing 31 and the second bearing 32 are tapered roller bearings. The advantages of tapered roller bearings include high load-carrying capacity, self-aligning capability, and wide applicability.

[0063] In this first embodiment, the rotating shaft 2 also includes a mounting part 23, which is fixedly connected to the outer wall of the first shaft body 21.

[0064] In this first embodiment, the first shaft body 21 includes a first shaft segment 211 and a second shaft segment 212 connected in sequence. The end of the second shaft segment 212 away from the first shaft segment 211 is fixedly connected to the second shaft body 22. The diameter of the second shaft segment 212 is larger than the diameter of the first shaft segment 211.

[0065] Specifically, in this first embodiment, the first external thread 2111 is provided on the first shaft segment 211, and the mounting part 23 is fixedly connected to the outer wall of the first shaft segment 211.

[0066] In this first embodiment, the first shaft segment 211 passes through the first through hole 111 of the first side plate 11 and the second through hole 611 of the third side plate 61, and the second shaft segment 212 passes through the first through hole 111 of the second side plate 13 and the second through hole 611 of the fourth side plate 63. That is, the first bearing 31 is disposed between the outer wall of the first shaft segment 211 and the hole wall of the first through hole 111 of the first side plate 11, and the second bearing 32 is disposed between the outer wall of the second shaft segment 212 and the hole wall of the first through hole 111 of the second side plate 13.

[0067] See Figures 1-6 ,and Figure 8 The flipping device 100 provided in Embodiment 1 of this utility model also includes an adjusting nut 7, which has a second threaded hole 71.

[0068] The locking nut 5 includes a first limiting part 51 and a tube part 52. The tube part 52 has a first threaded hole 521 and a second external thread 522 on its outer wall. The first limiting part 51 is connected to the end of the tube part 52 away from the mounting base 1. The adjusting nut 7 is threaded to the second external thread 522 through the second threaded hole 71, and one end of the adjusting nut 7 abuts against the bearing part 3. In this way, the bearing part 3 can be squeezed by tightening the adjusting nut 7 during reassembly, so as to achieve self-alignment and reduce the assembly clearance, thereby helping to further reduce the shaking of the seat during the flipping process.

[0069] Specifically, in this first embodiment, one end of the adjusting nut 7 abuts against the first bearing 31.

[0070] See Figures 1-9The flipping device 100 provided in Embodiment 1 of this utility model further includes a flipping assist component 8; the flipping assist component 8 is connected to the rotating shaft 2 and the mounting bracket 6 respectively. The flipping assist component 8 can both offset part of the weight of the seat body when the seat changes from a sitting state to a folded state, allowing the seat body to be folded into the seat more smoothly, and also offset part of the weight of the seat body when the seat changes from a folded state to a sitting state, thereby reducing the external force required to flip the seat body; therefore, the flipping device 100 provided by this utility model can provide assistance during the flipping process of the seat through the flipping assist component 8.

[0071] The flipping assist component 8 includes a limiting member 81 and an assist spring 82.

[0072] Mounting bracket 6 includes a third side plate 61, a second base plate 62, a fourth side plate 63, a first support part 64, and a second support part 65. The third side plate 61 is connected to one end of the second base plate 62 and is connected to the first side plate 11. The fourth side plate 63 is connected to the other end of the second base plate 62 and is disposed opposite to the third side plate 61. The fourth side plate 63 is connected to the second side plate 13. Both the third side plate 61 and the fourth side plate 63 have a second through hole 611. The first support part 64 is connected to the third side plate 61 and / or the fourth side plate 63 and is located on the first side of the rotating shaft 2. The second support part 65 is connected to the third side plate 61 and / or the fourth side plate 63 and is located on the second side of the rotating shaft 2.

[0073] A second receiving groove 621 is formed between the third side plate 61, the second bottom plate 62 and the fourth side plate 63.

[0074] A limiting member 81 is disposed in the second receiving groove 621 and fixedly connected to the rotating shaft 2. The limiting member 81 has a first limiting wall 8121 and a second limiting wall 8122. The first limiting wall 8121 is located on the first side of the rotating shaft 2, and the second limiting wall 8122 is located on the second side of the rotating shaft 2. A boosting spring 82 is sleeved on the rotating shaft 2. The boosting spring 82 has a first acting arm 821 and a second acting arm 822. The limiting member 81 has a first position and a second position. When the limiting member 81 is in the first position, the first acting arm 821 abuts against the first support part 64, and the second acting arm 822 abuts against the second limiting wall 8122. When the limiting member 81 is in the second position, the first acting arm 821 abuts against the first limiting wall 8121, and the second acting arm 822 abuts against the second support part 65.

[0075] By employing a limiting member 81 and an assist spring 82, and since the limiting member 81 is fixedly connected to the rotating shaft 2, the rotation of the rotating shaft 2 will drive the limiting member 81 to rotate. Therefore, the rotation of the limiting member 81 can cause the contact position of the first action arm 821 and the second action arm 822 to change, thereby enabling the storage and release of the elastic potential energy of the assist spring 82, and thus achieving the purpose of assisting the seat during the flipping process through the flipping assist assembly 8.

[0076] In this embodiment, the assist spring 82 is a torsion spring.

[0077] In some other embodiments, the assist spring 82 may also be any spring, such as a tension spring or a compression spring, that can assist in the flipping process of the seat by storing and releasing elastic potential energy, and is not limited here.

[0078] In this embodiment, both the third side plate 61 and the fourth side plate 63 are connected to the first support portion 64.

[0079] In other embodiments, the first support portion 64 may be connected to only the third side plate 61 or only the first support portion 64 may be connected to only the fourth side plate 63, and this is not limited here.

[0080] In this embodiment, both the third side plate 61 and the fourth side plate 63 are connected to the second support portion 65.

[0081] In other embodiments, the second support portion 65 may be connected to only the third side plate 61 or only the fourth side plate 63, and this is not limited here.

[0082] In this embodiment, when the seat body is in the unfolded state, the limiting member 81 is in the first position, and when the seat body is in the stored state, the limiting member 81 is in the second position.

[0083] The working process of the flipping assist component 8 provided by this utility model is as follows: When the seat body is in the unfolded state, the limiting member 81 is in the first position. At this time, the first action arm 821 abuts against the first support part 64, the second action arm 822 abuts against the second limiting wall 8122, and the assist spring 82 accumulates spring potential energy. When the seat body is driven to rotate around the first axis to flip the seat body upward through the rotating shaft 2 and the connecting member 4, the assist spring 82 releases the spring potential energy to offset part of the gravitational potential energy when the seat body flips upward, thereby reducing the external force required to flip the seat body upward and thus providing an assisting effect. When the seat body flips upward to the preset position, the first action arm 821 begins to... When the seat body contacts the first limiting wall 8121, the second actuating arm 822 begins to contact the second support part 65. When the seat body passes the preset position and needs to be flipped down to the second position, the force of the first actuating arm 821 against the first limiting wall 8121 gradually increases and the force of the second actuating arm 822 against the second support part 65 gradually increases. This causes part of the gravitational potential energy that offsets the downward flipping of the seat body to be gradually converted into the elastic potential energy of the assist spring 82 to play a buffering role. In turn, the assist spring 82 can slow down the speed of the seat body flipping down, thereby improving the maneuverability of the seat body when flipping down, until the limiting member 81 is in the second position and the seat is in the storage state.

[0084] When the limiting member 81 is flipped to the preset position, the assist spring 82 returns to the preset state. This preset state can be either the natural extension state of the assist spring 82, that is, the state in which the assist spring 82 does not accumulate elastic potential energy, or the minimum compression state of the assist spring 82, that is, the state in which the assist spring 82 accumulates the minimum elastic potential energy.

[0085] In this first embodiment, the flipping assist assembly 8 also includes a bushing 83, which is disposed between the outer wall of the first shaft 21 and the inner wall of the assist spring 82. By disposing the bushing 83 between the first shaft 21 and the assist spring 82, friction and noise can be reduced.

[0086] The limiting component 81 includes a connecting plate 811 and a second limiting part 812. The connecting plate 811 is located between the third side plate 61 and the bushing 83. The connecting plate 811 has a mounting hole 8111, and the connecting plate 811 is sleeved and fixed to the mounting part 23 through the mounting hole 8111. The second limiting part 812 is fixedly connected to the connecting plate 811 and has a first limiting wall 8121 and a second limiting wall 8122. The two ends of the bushing 83 abut against the connecting plate 811 and the fourth side plate 63, respectively. By abutting the two ends of the bushing 83 against the connecting plate 811 and the fourth side plate 63, the locking nut 5 can be tightened during assembly so that the locking nut 5 and the bushing 83 can approach each other and press against the connecting plate 811, thereby tightly fixing the connecting plate 811 and the rotating shaft 2 together.

The end of the first seat body 200 away from the second seat body 300 is connected to a flipping device 100, and the end of the second seat body 300 away from the first seat body 200 is connected to the flipping device 100.

[0094] Specifically, both the first seat body 200 and the second seat body 300 are connected to the connector 4 of the flipping device 100.

[0095] Existing split-type seats suffer from a lack of effective control over the assembly gap between the pivot 2 and the through hole of the mounting base 1 in their flipping device 100. This makes it difficult for the flipping device 100 to achieve the unilateral flipping function of the seat body. Consequently, an auxiliary support is required between the two seat bodies to connect them and achieve the flipping function while meeting the seat's safety requirements. However, when the seat body is folded, the auxiliary support creates a protrusion between the two seat bodies, reducing the flatness of the split-type seat when folded. In contrast, the split-type seat provided in Embodiment 3 has a flipping device 100 that improves the coaxiality of the pivot 2 and the mounting base 1, thereby reducing the assembly gap between the pivot 2 and the through hole. This allows the flipping device 100 to achieve the unilateral flipping function of the seat body while meeting the seat's safety requirements. Consequently, an auxiliary support is not required between the two seat bodies, thus avoiding a protrusion between them when folded and improving the flatness of the split-type seat when folded.

[0096] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
